摘要：

页岩气资源评价方法不同于常规油气资源评价方法。基于我国页岩气勘探开发现状，结合《全国页岩气资源潜力调查评价及有利区优选》工作要求，针对页岩气聚集机理和特点，提出了适用于我国现阶段的页岩气资源评价方法，即概率体积法。在统计分析我国泥页岩和页岩气相关参数基础上，建立了页岩气远景区、有利区和目标区优选参数体系，提出了不同类型页岩气选区标准和页岩气资源评价主体工作流程。结合国内外数据统计，确定了页岩气资源评价时的起算条件。根据离散型和连续型参数分布特点，研究了参数获取和概率赋值方法。研究成果为我国系统地页岩气资源评价提供了基础和依据。采用该方法对全国页岩气资源进行了评价，获得了地质资源量、可采资源量及有利选区结果，取得了良好效果。

Abstract:

Abstract: The assessment method of shale gas resources can differ completely from that of conventional hydrocarbon. Combined the present exploration and development situation of shale gas in China with the demands of “The national survey and evaluation of shale gas resource and favorable area selection”, a new method and technique for shale gas assessment is proposed, namely the probability volume method, based on the shale gas accumulation mechanism and characteristics. According to the shale gas geological recoverable conditions and statistical analysis, the parameters system for determining shale gas prospect areas, favorable areas and target areas is established. Furthermore, criteria for shale gas targets selection of different types and work flow for shale gas resources evaluation are put forward. Combining domestic and USA shale gas statistics data, this study laid the foundation of evaluation conditions for systematically assessment of the shale gas resources in China. Resource assessment parameters can be classified as discrete and continuous ones, which can be obtained and possibility assigned according to their distribution characteristics. Probability volume method and technique are applied in the Chinas first systematical shale gas resource assessment and work well.
